The Argentinian, who came from Boca Juniors, has been out since Round Two with an ear injury.

The original injury was sustained from a knock in the Round One 1-0 away win over Wellington Phoenix before he damaged it further in the 4-1 win over Melbourne.

The Argentine subsequently had trouble hearing and required surgery.

He made his return in Sunday’s 2-1 victory over Wellington Phoenix playing the final 15 minutes of the game.

 “I feel alright, thanks to the support of my partners, my coach, my family and the doctor,” Colazo said.

“I hope to play with my partners on Wednesday and take the win, it’s important for the club and for this team.

“I don’t think I’m 100 per cent, I feel alright, physical, I hope I stay there, doesn’t matter on the bench or on the pitch, fighting with my partners for FFA Cup.”

Colazo said captain and fellow South American striker Bruno Fornaroli was influential in his getting him to Melbourne.

“For me I spoke with Bruno, he told me about the league, it’s a beautiful league, good players and he said it was a big opportunity for you so I took it,” he said.

“Maybe the football in Argentina is more technical, here too, but it’s more physical, a lot more running and it’s good for me.

“I need to focus in this team because yesterday I took the ball and there were three guys with me and I realised I need to be faster with the ball and not as technical.”

City defensive midfielder Neil Kilkenny, who has experience playing in the Championship in England and featured in the 2011 Asian Cup Final for the Socceroos, stressed the importance of victory.

“The club is going places, the City group placed a lot of money into the club, it’s a fantastic facility we have here and they want success as much as us, as individuals and as a team,” Kilkenny said.

“We knew when we signed here, that’s what they want, they want success and when you play for big teams you have to bring success, it’s very important to win on Wednesday night, we’re all looking forward to it.

“We spoke to Bryan (Managing Director of City Football Services Bryan Marwood) and people at the club, they want success, we know that, that’s what they want.

“They drum into you when you sign and as individuals we want that as well, we want to create that buzz around the winning mentality and determination.”
